Magnetic separator products overview:
Magnetic separator is one of the most widely used and widely used machines in the industry field. It is suitable for the separation of magnetic materials with different magnetic properties. Magnetic separator is widely used in mining, timber industry, ceramics, chemical, food and other industries. And for mining, magnetic separator for size 50mm of manganese ore, magnetite, pyrrhotite, roasted ore, ilmenite, hematite and limonite etc. material wet or dry magnetic separation, but also for coal, non metallic minerals, building materials and other materials in addition to iron. Magnetic separator is divided into two categories, permanent magnetic separator magnetic system, multi use high-quality ferrite materials or with the rare earth permanent magnet compound and into, earlier, magnetic separator magnetic Jane surface average magnetic induction intensity for 80-400mT. With the continuous development of technology, magnetic separation can be made after the magnetic field strength also increased to 1650mT, is already the highest measured magnetic field strength.
Main features of magnetic separator:
Magnetic particles in magnetic separator magnetic field, in addition to the role of magnetic force, but also by the role of competition. Competitiveness can be defined as the force of the force that is opposite to the magnetic force, including gravity, centrifugal force, inertia force, and fluid resistance. In the magnetic separation process, the magnetic force is a collection of magnetic particles, also known as the magnetic capture force; competitiveness is to make the magnetic particles out of the power of the word, also known as the detachment force. Obviously, the necessary condition for the separation of magnetic and non magnetic particles is that the magnetic particles are more competitive than the magnetic force. If you want to make two kinds of magnetic separation of particles, the necessary condition is that the strong magnetic particles by the magnetic force should be greater than the competitiveness of weak magnetic particles by the magnetic force should be less competitive. Need to explain, in the practice of magnetic separation impossible absolutely pure magnetic products and non magnetic products, unless the monomer dissociation of intergrowth affect the purity of the product, some monomer magnetic particles mixed with non magnetic products, some monomer non magnetic particles mixed with magnetic products. A, leading to magnetic component recovery rate decreased, the main reason is the magnetic particles are too fine grained, magnetic force is not sufficient to customer service fluid resistance competitiveness; after a result of magnetic products taste decreased. The most likely cause between the particles exist strong interaction force, particle size is fine, the greater the slurry concentration, the more obvious the interaction force between the particles.
Working principle of magnetic separation machine:
Pulp to ore tank flows into the tank, in the role of the water mineral water spray to the next, mineral particles is loose state into the slot to the mine. Under the action of a magnetic field, magnetic mineral particles magnetically together and form a "magnetic group" or "flux", "magnetic group" or "flux" in the pulp by magnetic force, moving toward the poles, and is adsorbed on the cylinder. Due to the polarity of the magnetic poles along the direction of rotation of the cylinder are arranged alternately, and fixed at work, "magnetic group" or "flux" in with the cylinder rotates, due to the alternating magnetic pole and magnetic stirring phenomenon is mixed gangue in "magnetic group" or "flux" non magnetic mineral in turning off, was eventually absorbed on the surface of a cylinder "magnetic group" or "flux" is concentrate. Concentrate with cylinder turned to the magnetic edge of a magnetic weakest place, at discharging ore hoses flushing under the action of water is discharged into the concentrate slot. If the magnetic magnetic stick, unloading ore is brush Kun. The non-magnetic or weakly magnetic minerals are left with the pulp in the pulp tank to exclude, which is tailing.
Basic mechanism of magnetic separation machine:
Permanent Jane type magnetic separator mainly consists of cylinder, Queensland copper, brush Kun, magnetic system, a tank body, a transmission part 6 part composition cylinder by 2-3mm stainless steel plate coiling welded into a tube, end cover for Chou companion parts or components, stainless steel screw nails and tube connected. The motor drives the cylinder, the magnetic field and the brush to rotate through the speed reducer or the direct use of the stepless speed regulating motor. The magnetic system is an open magnetic system, which is arranged on the floor of the magnetic yoke with a cylinder and a bare magnetic block, and the magnetic block is installed on the floor of the magnetic yoke. Pulled the crank arm can adjust the magnetic declination lines, after proper adjustment can be fixed by a pull rod, the working area of the tank stainless steel plate and other parts of the frame and the groove with ordinary steel welding.
